Abstract . - Result s o f fie ld wo rk in the Gobi De sert . carried out in Bayn Dzak in 1967, 1968 and 196') arc briefly de­scribed. The course and result s of the Polish-Mongolian Pal aeontological Expeditions to various localities in the Gobi

D esert in 1970 and 1971 are di scu ssed . The main achievement of the 1970 and 1971 expeditions was the di scovery thatthe Lower Ncmegt Beds (possibl y Carn panian), previously regarded as unfossilifc rou s, contain ed a rich and varied fauna.

This fauna was found in the localiti cs of Ncrncgt, Khulsan a nd Khcrmeen T sav 11. The Soviet-Mongolian Exped it ion

di sco ver ed in 1969 the locality of Khcrrneen Tsav I, containing the Low er and Upper Nemcgt Beds. This locality wasal so visited and thc first di scoveries of mammal s and lizards in thc Lo wer Nerncgt Beds were made there. The Lower

Nern cgt Bed s at th ese four localit ies yielded the foll owing : about 80 mammals, 260 lizards. few crocodilians, the sku ll

of an unknown pachycephalosaurid dinosaur. 3 spec ime ns of new ankylo saurid dinosaurs, numerous fragment ary ske leto nsand skulls of Prot ocerat ops sp .. inc omplete ske leto ns of sma ll carnivorous dinosaurs. tortoises, very numerous dinosaur

egg s and diplopod myriapod s. The expeditions al so carried o ut cxcavatory work in the Upper Ncmegt Bed s (Iatc Cam­

panian or Early Maastrichti an) in the loc alities of Nerncgt and Altan Ula, collecting there: 4 incomplete ske leto nso f ornithomimid dinosaurs, 2 fragment s of ske leto ns o f coeluroid dinosaurs. 2 ske letons o f Saurolophus angustirostris,and severa l fragments of the same spec ies . the sk ull wit h fra gmentary postcranial ske leto n o f a new pa ch yccphalosaurid

dinosaur, th e postcranial ske leto n of a large ankylo saurid dinosaur, tort oises and numerous isolated dinosaur bones.

In addition the expedition carried out excavatory wo rk o n a smaller sca le in Bayn Dzak , Toogreeg and SheercgcenGashoon.

1967, 1968 AND 1969 EXPEDITIONS

After the completion of the Polish-Mongolian Palaeontological Expeditions of1963-1965 (KIELAN-JAWOROWSKA & DOVCHI N, 1968/69) , field work in Mongolia for thePolish palaeontologists was suspended for one year.

In the years 1967, 1968 and 1969 three small expeditions were sent to the MongolianPeople's Republic by the Palaeozoological Institute of the Polish Academy of Sciences , tosearch for mammals in the Upper Cretaceous sediments of the Djadokhta Formation in BaynDzak (Shabarakh Usu) in the Gobi Desert. These journeys came within the terms of anagreement on the exchange of scientists between the Polish and Mongolian Academies ofSciences. The Polish palaeontologists were guests of the Mongolian Academy of Scienceswhich, on each occasion, delegated one person to accompany the group, also putting a carwith driver at their disposal. The 1967, 1968 and 1969 expeditions did not undertake anyexcavatory work but confined themselves to searching for fossil s in the outcrops of Cretaceoussandstone in Bayn Dzak.

In 1967, Eng, M. KUCZYNSK I and Mr. W. SKARZYNSKI spent from 23 September to23 October in Mongolia, two weeks being spent in Bayn Dzak. They were accompanied bytwo Pol ish geologists D r. J . l EFEl Dand D r. H. l..OBANowSKI, carrying out their own programme,and the Mongolian geologi st Mr. CEV EG .

In 1968, D r. H. OSMOl SKA, Mr. W. SKARZYNSKI and Prof. Z. KIElAN-JAwORowSKAwere in Mo ngo lia from 16 July to 7 August. Most of this time was spent searching for fossilsin Bayn Dzak. The y were accompanied by Mr. DovcHIN, a technical assistant in the Institu tcof Biological Sciences of the Academy of Sciences in Ulan Bator.

In 1969, D r. H. OSMOl SKA, Dr. A. SUlIMS KI and Prof. Z. KIEl AN-JAwORowSKA spentfro m 25 Ju ly to 13 August in Mongolia , working most of the time, as in the p revious yea r,in Bayn Dzak. The Polish gro up was acco mpa nied by the Mongolian pa laeo nto logistMrs. P. NARMANDACH .

Du ring these 3 ycar s, 20 mamm al specimens were collected (KIELA N-JAWORowSKA ,1969, 1970 a , 1970 b, 1971 ), more than 20 lizard s (SULlMSKI , 1972) as well as the fragmenta ryskeleton of a crocodile (OSI\10LSKA, 1972).

1970 EXPEDITION

Under the agreement signed in Ulan Bator in May 1969 between the Polish and Mon ­golian ' Aca demics of Sciences, 2 large Polish-Mongolian expeditions were to be organizedin 1970 and 197 1 to continue the work done in 1963-1965. The y were to work in the sameregions as in previous years, that is in Bayn Dzak and in the Nemegt Basin and surroundingarea (GRADZINSK I et al., 1968/69 ). The expeditions were to bc organized on the same principlesas tho se of 1963-1965 (KIElAN-JAWOROWSKA & DOVCHIN, 1968/69), but with th is differencethat the cost of equipment , engaging work es and transporting the collections were to be covere dsolely by the Polish side.

The tra nsport for the 1970 exped ition con sisted of 2 car s brought from Poland (a Po lishtruck Star 660 and a jeep type Roman ian ca r MS 46 1) as well as a truck of Soviet pr oductionGas 63 , hired in U lan Bator toget her with Mo ngolian driver. In addition, several extra truckswith trai lers were hired to take the equipment fro m U lan Bato r to Bayn Dzak and Gu rvanTes in the Nemegt Basin and transport the collections bac k to Ula n Bator .

The 12 Polish members of th e Expedit ion were:I. Mr. ADAM GLODZINSKI - doctor and cook2. Doe. RvszARD GRADZINSK I - geologi st, vice-leader3.

The Mongolian group consisted of 3 persons:1. Or. RINCHEN BARSBOLD - palaeontologist, leader of the Mongolian group, who did not

actually take part in the expedition , but visited it twice in the field2. Mr. DEMBERLYIN DASHZEVEG, M. Se. - palaeontologist (with the expedition from 8 to

22 July)3. Mr. ALTANGER EL PERLE, M. Se. - palaeontologist.

In addition to the above, one Mongolian worker was engaged in Ulan Bator for thewhole period of the expedition and 6 extra workers hired for the period 10 August - 26 Sep­tember.

All the necessary equipment including car s, was dispatched by rail from Poland on12 May, arriving at Ulan Bator on 15 June , where it was received by the Mon golian side.On 23 Jun e, a four person techn ical group - KUCZYNSKI , MACZEK, SZANIAWSKI and SKAR­ZYNSKI flew to the Mongolian capital. During two weeks they unloaded the equipment andhad it taken to Bayn Dzak and Gurvan Tes, where the stores for the expedition were estab­lished.

On 3 July, thr ee other members of the expedition (K IELAN-JAWOROWSKA, URBANEK,GRADZINSKI) arrived by air in Ulan Bator. At a meeting next day, the leaders of the Polishand Mongolian sides set down the programme of work for the expedition. On 6 July the re­maining fi ve members joined the expedition.

On 7 and 8 July the members of the expedition set out in two groups for Bayn Dzak(see Text-fig. I), where they remained until 21 Jul y. ln Bayn Dzak a few incomplete mammalskulls and many lizards were found . In addition , a skeleton, skull and several fragments ofskeletons of Prot oceratops andrewsi (see GRANGER & GREGORY, 1923, BROWN & SCHLAIKJER,1940) , a pelvic gird le and hind limb s of Pinacosaurus sp. (see MARYANSKA, 1971) as well asseveral dino saur eggs were recovered.

While in Bayn Dzak a party of five (GRADZINSKI , KIELA N-JAWOROWSKA, MACZEK ,OSI\10LSKA and DASHZEVEG) went between 13 and 16 July to the Guchin Us outcrops, situatedabout 200 km NW of Bayn Dzak, where mammal-bearing Lower Cretaceous sediments,which had been explored by the Soviet-Mongolian Palaeontological Expedition occur. Between17 and 19 July, a second party (GRADZI NSKI, MARYANSKA, SZANIAWSKl and URBANEK) madea trip to investigate Cretaceous outcrops in the vicinity of Dalan Dzadgad .

On the 21 July the camp in Bayn Dzak was wound up and the expedition proceededto the outcrops of Nemegt (GRADZI NSKI & JERZYKIEWICZ, 1972) in the Nemegt Basin, to carryout excavatory work in the Upper Cretaceous sediments referred to as the Upper NemegtBeds and to search for fossils in the Lower Nemegt Beds (GRADZINSKI et al., 1968/69 ; seealso GRADZI NSKI, 1970 ; MARYANSKA , 1970 ; OSMOLSKA& RONI E.WI CZ, 1970 ; SZCZECHURA & BLA­SZYK, 1970; KARCZEWSKA & ZIEMBI NSK A-TwORZYDLO, 1970 ; NOWINSKI, 1971; KHOSATZKY &MLYNARSKl, 1971) .

During the 2 month stay in Nemegt the following specimens from the Upper NemegtBeds were recovered:I. Two incomplete skeleton s of Tarbosaurus sp. (see MALEY EV, 1955a, 1955b ; ROZHDEST­

VENSKY, 1965) and several fragment s of the skeletons of the same species.2. One almost complete skeleto n and some fragment s of the skeletons of Sauroloplius angusti­

rostis ROZHDESTVENSKY (ROZHDESTVENSKY, 1957).3. One almost complete postcranial skeleton and some fragmentary skeletons of orn ithomimid

dinosaurs (OSMOLSKA, RONI EWICZ & BARsBoLD, 1972).4. Two fragments of skeletons of small coeluroid dino saurs.5. Very well preserved skull and fragment of postcranial skeleto n of a new repre sentative

of the Pachycephalosauridae.6. Numerous tortoises (MLYNARSKI & NARMANDA CH, 1912) .

In addition , sedimentological observations were carried out and numerou s samples formicropalaeontological investigations collected.

While in Nemegt three journeys were made to the outcrops of Altan Ula , some 50 kmto the west of Nemegt (between 2 I and 25 Augu st : GRADZI NSKI , OSMOLSKA, SKARZYNSKIand SZANIAWSKI; between 30 Augu st and 2 September : GLODZINSKI , NOWINSKI, SICINSKI,SKARZYNSKI, URBANEK and 4 workers ; between 9 and I [ September : GRADZINSKI, MACZEK,MARYANSKA and PERU:). During these journeys an incomplete skeleton of Tarbosaur s bataar,fragments of a skeleton of Saurolophus angustiro stris and fragmentary limb of an ornithomimiddinosaur were excavated . Between 30 August and 5 September GRADZINSKI , KIELAN-JAWO­ROWSKA , MACZEK , MARYANSKA and PERLE set out on a reconnaissance to the SheeregeenGachoon Basin, situated north of the Nemegt range . Here they collected in Cretaceous sedi­ments a few dinosaur remains and a carapace of a tortoise (MLYNARSKI & NARMANDACH,1972). Th e exact age of these sediments has not been defined .

In the second half of the stay in Nemegt, work was mainly concentrated on the LowerNemegt Beds, which underlay the Upper Nemegt Beds. The Lower Nemegt Beds crop outin two localities : in the eastern and southern part of the locality of Nemegt , in the areas de-

signated Southern Monadnocks, Red Monadnocks and Red Walls and in the locality of Khu l­san (GRADZINSKI & JERZYKI EWICZ, 1972, Text -figs. 3 and 4). The Lower Nemegt Beds wereregarded by EFREMOV (1950, 1954) as unfossi liferous and referred to as barren series. Thework in this series proved successful beyond expectation. Here were found fragmentary skeletonsof Proto ceratops sp., incomplete skull of an ankylosaurid dinosa ur, numerous dinosaur eggsof different sizes, about 80 lizards, diplopod myriapods, tortoises (MLYNARSKI, 1972) andskulls of mammals. In the course of 2 weeks, 22 mammalian specimens were collected , amongthem several near ly complete, well preserved skulls of mu ltituberculates and insectivore s.A preliminary investigation of the mammals collected, studied by the first author , indicate sthat the Lower Nemegt Beds are somewhat younger than the Djadokhta Formation , beingprobably of Campa nian age.

On 26 September the exped ition left Nemegt, arriving in Ulan Bator on 29 Septem berwhere the collections were divided for scientific study. The Polish members of the expeditionleft Ulan Bator in several groups dur ing Octobe r, the last gro up arr iving in Warsaw on25 October.

1971 EXPEDITION

After the 1970 expedition , part of the Polish equipment was left over the winter in UlanBator. New equipment for the 1971 expedition was sent by rail from War saw on March 15,arri ving on April 28 in Ulan Bator, where it was received by the Academ y of Sciences of theMongolian People's Republic. The tran sport for the expedition ~ons isted of 2 car s, left afterthe 1970 expedition in Ulan Bator (a Polish truck Star 660 and a jeep-type Romanian carMS 461), as well as a truck Gaz 63 of the Soviet production , hired in Ulan Bator toget herwith a Mongolian driver, for the whole period of the expedition. In addition two extra truckswere hired at the beginning to take the equipment from Ulan Bator to Gurvan Tes, and atthe end of the expedition, to tra nspo rt the coliection s from G urvan Tes to Ula n Bat or.

The 12 P olish memb ers of the expedition were:I. Mr. ANDRZEJ BALlNSKI , M. Se. - palaeontologist2. Mr. JAN BIJAK- doctor and cook3. Mr. ANDRZEJ EU:ANOWSKI - student4. D r. TOMASZ JERZYKI EWICZ - geologist5. Prof. ZOFIA KIELAN-JAWOROWSKA - pa laeontologist, leader of the Polish gro up6. Eng. MACIEJ KUCZYNSKI - technical leader and driver7. Mr. CYPRIAN KULlCK I, M.

10. Mr. WOJCIECH SKARZYNSKI - technica l assistant11 . Dr. ANDRZEJ SULlMSKI - palaeontologist12. Mrs. MARIA ZIEMBINSKA-TwORZYDLO, M. Se. - palaeobotanist.

Th e M ongolian group...consisted of 3 persons:1. Dr. RINCHEN BARSBOLD, palaeontologist, leader of the Mongolian group, not taking

actually part in the expedition2. Mr. ALTANG EREL PERU , M. Se. - palaeontologist3. Mr. SAMBU - technical assistant.

In addition to the above, 3 Mongolian workers were hired for a per iod of 26 Jun e to24 July.

On 28 April a four person technical group (K UCZYNSKI, l ERZYKIEWICZ, KULICKI andMIRANOWSKI) flew to Ulan Bator. During two weeks they unloaded the equipment and hadit tak en to Gurvan Tes, where the store for the expedition was establi shed .

On 11 May KIELAN-JAWOROWSKA and MAYRANSKA arri ved at Ulan Bator. During nextdays KIELAN-JAwORowSKA and BARSBOLD set down the programme for the expedition . On14 May the rema ining six Polish members joined the expedition .

On 16 May the expedition set out for Khulsan (see Text-fig. 1) in the Nemegt Basin,ar riving there on 20 May. In Khulsan the expedition stayed until 23 June. During thi s periodthe Lower Nemegt Beds at Khul san and Nernegt were explored (GRADZINSKI & JERZYKIE­WICZ, 1972). From the Lower Nemegt Beds in these two localities the following specimenswere collected: about 80 lizards, about 35 mammals, a few diplopods and numerous dinosaureggs of various sizes. In addition, at Khulsan the skull of a small pachycephalosauriddinosaur was found and the anterior part of the skeleton (skull and a half of the trunk) of anunknown ank ylosaurid dino saur. The excavation of this skeleton pro ved difficult, as it was foundin a cliff 4 m above the ground level, and it was necessary to build special scaffolding forits excavation. Whi le in Khulsan groups of several persons went twice to Khermeen Tsav(see below). "

On 23 June the camp at Khul san was wound up and the expedition proceeded to theoutcrops of Altan Ula IV in the Nemegt Basin, to carry out excavatory work in the UpperNemegt Beds (GRADZINSKI et al. 1968/69). During six weeks stay at A1tan Ula the followingspecimens from the U pper Nernegt Beds were recovered :I. The skeleton of a very large individual of Tarbosaurus sp. and one incomplete skeleton

of a small indi vidual of the same species, both from Altan Ula Ill.2 The incomplete skeleton, with well preserved skull of a small individual of Saurolophus

angustirostris ROZHDESTVENSKY, from Altan U la IV.3. Three fragmentary skeletons of ornith omimid dino sau rs, one from Alta n Ula 111 and two

from Altan Ula IV.4. The skeleton (without skull) of a very large ankylosaurid dinosau r from Altan Ula Ill.5. Turtles, isolated bones and fragment s of skeletons of various dino saurs from Altan Ula III

a nd IV.While in Altan Ula one journey to Khermeen Tsav and one to Sheercgcen Ga shoon were

organi zed.The expedition visited the outcrops of the Upper Cretaceous sediments at Khermeen

Tsav on three separate occasions: between 31 May and 5 June (JERZYKIEWICZ, KIELAN-JAwo ­ROWSK A, KUCZYNSKI, MARYANSKA; MIRANOWSKI and SKARZYNSKI) , between 11 and 17 June(EL:2:'ANOWSKI, KIELAN-JAWOROWSKA, KUCZYNSKI, KULICKI, MlRANOWSKI, PERLE and Su­L1MSKI) and between 28 June and 8 July (BALINSKI, BUAK, ELZANOWSKI, JERZYKI EWICZ, K u­LICKI , MARYANSKA, MIRANOWSKI and ZIEMBINSKA-TwORZYDLO).

The Cretaceous sediments of Khermeen Tsav were discovered by the second authorand Dr. V. ZHEGALLO in 1969, during the work of the Soviet-Mongolian PalaeontologicalExpedition (see BARSBOLD et al. 1971 ; KALANDADZE & RESHETOV, 1971). Khermeen Tsa vis an area of extensive badlands of Upper Cretaceous sediments, situated some 50 km south­westwards from Naran Bu1ak. They can be approached from the Nemegt Basin driving fromNaran Bulak about 28 km westwards along the E kheen Dzooganay Gal sayr. then turningsouthwards and driving 34 km south-westwards. The K herrneen Tsav badlands extend

NARRATIVE OF TH E POLIS H-MONGOLIAN EXPEDI TIONS 11

west-east and can be approached from the western end. The sed iments dip slightly south­westwards (GRADZINSKI & JERZYKIEWICZ, 1972) . In the lower part of the section there occurthe orange sand and sandstone with dark red sandy concretions, yielding Protoceratops sp .(probably Protoceratops andrewsiy . This sandstone passes upwards into yellowish-grey sa nd-

. stone, the latter yielding the bones and skeletons of big dinosaurs.In 1970 the Soviet-Mongolian Palaeontological Expedition carried out the excavatory

work in the upper part of Khermeen Tsav sect io n. The main aim of the trips of the Polish­Mongolian Expedition in 1971 to Khermeen T sav wa s to sea rch for mammals and lizardsin the beds yield ing Protoeeratops sp . In 1971 the Poli sh-Mongolian Expedition visited al sothe outcrops of the red sa ndstone, situated north to the Khermeen Tsav badlands, and sepa­rated from it by a belt of 3-5 km pediment. These beds were examined palaeontologicallyfor the first time on thi s occasion , and are designated Khermeen T sa v II (GRADZINSKI & JE­RZYKI EWICZ, 1972, Text-fig. 5), in contradistinction to the badlands of the true K hermeenTsav, designated Khermeen T sav I. From the sandstones that crop out in Khermeen Tsav IIwe collected fragmentary skeletons of Protoceratops sp., an incomplete skeleton of an ankylo­sa urid dinosaur, dinosaur eggs , a few diplopods, about 80 lizards and 24 specimens of mammal s.From the sa ndstones that occur in the lower part of the sect io n of Khermeen Tsav 1, we col­lected fragmentary skeletons of Protoeeratops sp ., dinosaur eggs, fragmentary skeletonsof sma ll carnivorous dinosaurs, about 20 skeletons of comparatively big lizards and 2 skullsof multituberculates. In contradistinction to the outcrops of Khermeen T sa v Il , the mammalsare very rare in the red sa ndsto ne of Khermeen T sav 1.

Preliminary investigation of the mammals collected in Khermeen T sa v ] and 11 , doneby the first author, shows that they belong to the same species as those found in the LowerNemegt Beds in Khulsan and Nemegt. This is the ba sis for the first author's conclusion thatthe sandstone of Khermeen T sav ] I and the red sandstone of Khermeen Tsav I are contempo­raneous with the Lower Nemegt Beds and belong possibl y to the Campanian. The yellowish ­grey sa ndstone which overlies th e red sa ndstone in Khermeen Tsav I would correspond to theUpper Nemegt Beds.

Between 12 and 19 July the party of six (J ER ZYKI EWICZ, K UCZYNSKI , MARYANSKA , MI­RANOWSKI , PERLE and SKARZYNSKI) set out on a trip to Sheeregeen Gashoon Ba sin. From th eCretaceous outcrops occurring there, they collected the postcranial skeleto n of a small theropoddinosaur, an almost complete skeleto n, entirely embedded in rock , of a small, unidentifiedreptile and several isolated dinosaur bones.

On 3 August the expedition wound up the camp at Altan Ula and proceeded to thelocality of Toogreeg (Toogreegeen Shire) situated some 30 km westwards from Bayn Dzak.Cretaceous sediments at Toogreeg are white-yellowish sand and sands tone, yielding Proto­eeratops andrewsi, dinosaur eggs and sm all theropod dinosaurs. The expedition collected heretwo skulls and two skeletons of Protoeeratops andrewsi, as well as the skeleton ofa Ve/ociraptormongoliensis preserved together with the skeleton of Protoeeratops andrewsi, The sta te ofpreservation of those two skeletons ( Velociraptor embraces with its fore-limbsthe skull of Protoeeratops) shows that their preservation in association is not accidental andthat they possibl y died during the fight.

On 12 August the expedition wound up the camp at Toogreeg, returning to Ulan Batoron 19 August. The assembled collection was divided for scient ific study between the Polishand Mongolian Academies of Sciences. The Poli sh members of the expedition left U la n Bato rin severa l groups, the last group arriving in Warsaw on 14 September.
